Hm... now I'm thinking into which DT field should I put atags and 
revision. In previous emails you wrote to use "linux,atags", now 
"arm,atags"? And put them into root node? Or other?

In arch/arm/boot/compressed/atags_to_fdt.c code I see that most atag 
properties are converted into "/chosen" node in DT...

So what do you prefer for "revision" and what for "atags"?

Some mentioned examples:

"/revision"
"/chosen/revision"
"/linux,revision"
"/chosen/linux,revision"
...

"/atags"
"/chosen/atags"
"/linux,atags"
"/chosen/linux,atags"
"/arm,atags"
"/chosen/arm,atags"
...
